you should have Binance/exchange/advanced tab for BTC (e.g.), on a screen behind you. Visible chart, beautiful graphics, combined with some kind of referrall link warning, new customers would immediately get hooked, and visit Binance through your link. Great opportunity+ nice looking screen behind you. You solve two problems at once and no one can complain because you silentely promoting exchange that is actually doing something good and is working towards decentralization!
